You could try Google Chrome as browser. This has Flash 11.7 built-in.
Yes, 11.7 for Linux, while 11.2 is the "official" latest release for Linux. How? Because Chrome uses the Pepper API for which Adobe is still developing.
As Google mentions on their support page:
Linux users: Adobe Flash Player uses a cross-platform API, Pepper API
(PPAPI), to run its plug-in in Chrome. You might notice some of the
known issues below specific to Linux Chrome:
- Mouse locking may not work.
- Viewing Adobe Access (DRM) content is not supported, since Adobe does not support it on Linux.
- Stage3D content will always be rendered through software.
- Adobe Connect in presenter mode will not work with this version of the Flash Player.
- Installing Adobe AIR Desktop applications from the web will not work. This includes applications such as Pandora’s Desktop music player, Tweetdeck, Flickr Desktop Search, Twhirl and Amazon’s Music Downloader.
- Installation of the Octoshape Grid Delivery Enhancement will fail.
This has been announced in 2010 on the Chromium Blog. Note that Chromium does not have a bundled version of Flash included (and therefore requires the installation of the 11.2 version).
Example: on google-chrome-stable version 28.0.1500.52-r207119, runs version 11.7.700.203 of Flash as you can see below.
